' WHEEL-HUB.

Specification of Letters Patent. Patented Mar. 26, 1912. Application filed January 16, 1911. Serial No. 602,929.

To all whom it may concern: &

. Be it known that I, FRIEDRICH W. J." GoERsoi-I, a subject of the Elm eror of Germany, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have 1nvented' a new and useful Wheel-Hub, of which the. following is a specification.

It is the object of the present inventionto provide an improved wheel hub of the cushioned type. Ordinarily, such hubs embody a central member and aymember surrounding the central member and spaced therefrom by radially arranged springs. Such a construction is however bulky and the s rings are liable to become disarra'nged and furthermore it is diificult to so arrange the springs that they may have their tension adjusted, without so complicating the structure as to render it too expensive for eneral use. The present invention thereore aims primarily to so construct the wheel hub that it will be little if*any larger than the ordinary wheel but, it will act in a highly efiicient manner as a'cushionfor the remainder of the wheel, and may be so adjusted as to respond more or less readily to impact or strain, depending upon the character of the vehicle in the construction of the wheels of which it-is embodied.

With the above and other objects in view the invention resides in the general construction and arrangement of parts substantially as claimed and shown in the accompanying drawings in which Figure 1 is a vertical longitudinal sectional view through a wheel hub constructed in accordance with the present invention.

Fig. 2 is a side elevation thereof, the cap for the hub bein' removed and parts of thehub being bro en away. Fig. 3 is a perspective group view of several members of the hub, they being arranged in position to be assembled one with another. Fig. 4 is a sectional view on the line 44 of Fig. 1.

In the drawings, the hub is illustrated as including, in its structure, a-central member comprising a sleeve 5 and a head 6 located at one end of the sleeve. The sleeve 5 is to be shrunk or otherwise secured on rotating axles and-rotatably mounted on fixed axles. The head 6 upon the sleeve 5 is formed, in its face which is presented toward that end of the sleeve opposite the end in which it is located, with radially alined diametrically oppositely located grooves 7. An annular slide plate 8 is formed upon one face with diametrically oppositely. located radially alined lugs 9 and upon its opposite face with v The plate is disposed against the said face of-the head 6 w1th its lug 9- seating in the grooves 7. It will be observed that the plate 8 is of the same diameter as the head and that it is of such diameter at its inner periphery as to loosely receive the sleeve 5 and allow relative movement of the head and sleeve and the said plate. Thehub ineludes also a body member which is substantially annular in form and is indicated in the drawings by. the numeral 11. This member is provided with spaced flanges 12 and 13 and the flange 12 is formed upon its outer face with semi-annular raised por- 'tions 14 the spaced ends of which provide grooves 15 in the said face of the-body member, these grooves being radially 'alined and diametrically oppositely located and receiving the lug 10 upon the slide plate 8. An annular cap member 16 is bolted or otherwise secured to the flange 12 and holds the head 6 and slide plate 8 against the body member 11 in the position illustrated in 'Fig. 1 of the drawings, itbeing understood that the head 6. may have sliding movement with respect to the slide plate and that the head and slide plate may have sliding movement upon the outer face of the flange 12 of the body member, the engagement of the lugs 9 and 10 in the grooves 7 and 15 permitting of such relative movement ofthese part-s and at the same. time constituting a means for holding the body member 11 for rotation with the sleeve member 5.

The spokes of the wheel are indicated by the numeral 17 and at their inner ends are located between the flanges 12 and 13 of the.

body member 11, it being understood that. at their outer ends theysupport the wheel felly. Inorder that movement of the wheel felly with respect to the hub may be properly cushioned, there is provided'an arrangement of elements which will now be described. At its side opposite the side at which the flange '12 is located. the body member of the hub is formed with a conical socket 18 in which is fitted a cone 19 formed at one end of a sleeve 20. thissleeve being slidably fitted upon the sleeve 5 and being held normally toward the body member 11 by means of a spring 21 which is fitted upon similar lugs 10 located however in alinement at right angles to the first mentioned lugs.

ios

the sleeveand bears at one end against the cone 19 and at its other end against a nut 92 which is adjustably threaded upon the sleeve 5, adjustment of this nut upon the said sleeve 5 serving to adjust the tension of-the spring 21 and cause the cone 19 to bear more or less firmly in the socket 18. It will at this point be readily understood that the opening in the body member 11 is to be of greater diameter than the sleeve 5 so that the sleeve may work freely in the member and upon movement of the sleeve in any direction, the cone 19 will be, partly forced from its socket 18 against the tension of the spring 21, relative movement of the sleeve 5 and its related parts and the body member 11 of the hub, carrying the spokes 17 being in this manner cushioned. A cap 23 is preferably fitted over the outer end of the sleeve 5, the sleeve 20, and the socketed face of the body member-11 so as to exclude. dust from these parts and'also to retain any lubricant which may be employed in lubricating the'lnoving parts of the hub.

Vhat is claimed is: I,

1. In a Wheel hub, a body member formed with a conical socket, a sleeve member loosely'fitted to the'body member and hav-- ing a head slidably resting against one face of the body member, a nut adjustably mounted upon the inner end of the sleeve,

and a spring sleeve member and bearing in the socket.

2. In a wheel hub, a body member formed with a conical socket, the member being formed in the outer face with radially alined grooves, a sleeve member fitted through the ody member and arranged to have play therein, an annular head formed at one end of the sleeve member and formed in one face with radially alined grooves, a slide plate fitted between the head upon the sleeve, and the body member and having lugs upon its opposite faces Working in the grooves in the said end of thesleeve member and the said face of the body member, a cone carried by the sleeve adjacent the socket of the body member, a nut adjustably mounted upon the other end of the sleeve, and a spring surrounding the .sleeve between the nut and cone to exert a spring tension upon the cone and retain the head cushionedly in contact with the outer face of the body member.

In testimony that I claimthe foregoing as my oWn,-I have hereto afiixed my signature in the presence of two witnesses.
